In today’s digital world, data privacy is paramount. While cloud services like Google Drive or Dropbox provide easy file sharing, they may not always align ...
The recipients retrieve the encrypted data and decrypt it themselves
Ok, but how can the recipient decrypt it if he doesn’t have the key? The only thing that’s shared is the URL and if the key is in the URL, well, I don’t know what’s the use for it since the server knows it.
@peregus It’s explained in other threads here. The key is in the url but behind # and that part is invisible to the server. protocol://host:port/path?query#fragment, server will only see …?query, so both participants can decrypt, but server can’t => E2EE
Oh, ok, now I get it. So it could be checked by a third party if that code is really created by the browser and if it’s not sent to the server, correct?
@[email protected] but the owner of the server could change it, could it be checked directly on the webpage of the service?
Not that I will do it (I can’t, I can’t read that code), I’m just curious.

@peregus Apparently some of your assumptions must be incorrect
Do you mind sharing with us what’s incorrect? I’m here to learn.

But it’s the server that creates the URL in the first place, so it must knows it, right? …or wrong?
@peregus No that would be created by javascript in the sender’s browser.

@peregus yes, that would be here: https://github.com/timvisee/send/blob/master/app/fileSender.js#L81
